Best Prayer Scripture?
 

For those who don't pray but meditate, an axiom will do.

For me, Romans 8:26 and 27.

26 Likewise the Spirit also ahelpeth our infirmities: for we know not what we should bpray for as we ought: but the Spirit itself maketh cintercession for us with dgroanings which cannot be uttered. 27 And he that asearcheth the hearts knoweth what is the mind of the Spirit, because he maketh bintercession for the saints according to the will of God.
